PRO-SW100P 100-Watt Powered Subwoofer
Your subwoofer has an adjustable high cut filter and high and low level in­puts, making it easy to incorporate into existing systems, or you can use it as an integral part of a subwoofer/satellite combination.
It also has these features:

Your Optimus PRO-SW100P 100-Watt Powered Subwoofer is designed to give you the best possible low fre­quency sound quality for the ultimate home theater experience. You will be astonished by the realism it adds to movie sound effects and the power it lends to all kinds of music.
The subwoofer com bin es the power of a built-in 100-watt RMS amplifier with a responsive, 10-inch coated paper cone woofer — all housed in a ported bass-reflex enclosure to prod uce tight, floor-rumbling, powerful bass (down to 42 Hz) that you can feel as well as hear! The LED power indicator lets you see at a glance when the sub­woofer is operating.

SAFETY INSTRUCTIONS
• Never open the cabi net or remove the metal control panel, as this might result in electrical shock or damage to the unit.
If your PRO-SW100P needs ser­vicing, contact your local Ra­dioShack store.
• To prevent electrical shock, do not use this polarized plug with an extension cord receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure.
• Unplug the PRO -SW 100P’s power cord from the electrical outlet if it will be left unused for a long time.
• Only connect this uni t to a power supply of the type desc ribed in t he operating instructions or marked on the unit.
• Route the power-supply cord so it is not likely to be walked on or pinched by items placed upon or against it, especially a t plugs, con­venience receptacles, and the point where it exits from the unit.
• Placing the subwoofer on the same stand or shelf as your turnta­ble can result in low frequency rumble or acoustic feedback.
Cautions :
• To prevent fire or shock, do not expose this subwoofer to rain or moisture.
• Do not place the subwoofer with its metal plate against the floor.

Page 3
40-408 0.fm Page 3 Wednesday, August 11, 1999 10:58 AM
• Place the subwoofer away from heat sources such as radiators, stoves, or other appliances that produce heat.
CHOOSING A LOCATION
Cautions:
• To prevent the ca binet from warp­ing or discoloring, do not place the subwoofer in a place where it is exposed to direct sunlight or excessive humidit y.
• Do not place the subwoofer where it might be knocked over or exposed to falling objects.
• The metal control panel on the back of the P RO-SW1 00P acts as the heat sink for the subwoofer’s internal amplifier. Therefore, place the unit at least 4 inches (10 cm) away from a wall, and do not let anything come into contact with this panel.
Where and how you position your sub­woofer greatly affects its bass re­sponse. Adjusting the subwoofer’s volume control in relation to the left and right speakers and adjusting the subwoofer’s high cut filter also affects your speakers’ overall sound.
Although low frequencies are non- di­rectional, factors such as room reflec­tions, standing waves, resonance and absorption strongly affect your sub­woofer’s performance. For maximum bass output, place your subwoofer in a corner. To reduce output, move it away from corners and back walls. Even slightly moving the subwoofer
can have a major effect on bass re­sponse.
We recommend that you test the sub­woofer in different locations to deter­mine where the best balance is between your satellite speakers (if used) and subwoofer. We also recom­mend that you place the PRO­SW100P at least 4 inches a way from the wall, and at least 2–3 feet away from your television or computer’s disk drive system so the s ubwoofer’s mag­net will not distort the colors of your TV picture or erase your floppy disks.
CONNECTING TO AN AMPLIFIER
You can connect your PRO-SW100P to an amplifier/receiver’s line out or speaker terminals.
Notes:
• We recommend you connect the subwoofer to an amplifier or receiver that has at least two sets of line out j a cks. If your ampli fi e r o r receiver has only one set of line out jacks, you might not hear any sound f rom the s atellite spe akers. If your amplifier or receiver has only one set of line out jacks, fol­low the instructions under “Con­necting to Speaker Terminals” instead.
• Your PRO-SW100P can also be connected to your television if your television has line out jacks.

Connecting Speakers
You can connect your left and right speakers to your am plifier/receiver (as shown on Page 4), or to the PRO­SW100P’s speaker terminals (as shown above).
If you use MEGACABLE er high quality, low gauge speaker wire, th e terminals will be too sm all to accommodate the wires. You need two pairs of Speaker Pins (RadioShack Unlimited Cat. No. 10 458503 ) to m ake the connection. Follow these steps to connect the wires to each terminal us­ing Speaker Pins.

1. Rotate
2. Turn on your amplifier/receiver and another component (such as a radio, cassette player, CD player, or turntable).
3. Begin play of an audio source (such as a radio) and adjust the amplifier/speaker’s overall volume to a comfortable level. Rotate

ADJUSTING THE HIGH CUT FREQUENCY
FREQUENCY HZ
adjusts the level (be­tween 50 Hz and 200 Hz) at whi c h the subwoofer begins passing frequen­cies to other speakers. This control’s setting depends on the low frequen cy capabilities of your satellite speakers (if used), speaker placement, and oth­er factors that affect bass perfor­mance.
While playing music, rotate
CY HZ
clockwise until it sounds like the

music is too bass-heavy. Then rotate it counterclockwise until the bass sounds more natural.
If the mid-bass sounds natural but you want more low bass, rotate

CARE AND MAINTENANCE
Your Optimus PRO-SW100P 100-Wat t Powered Subw oofer is an example of su­perior design and craftsmanship. The following suggestions will help you care f or your subwoofer so you can enjoy it for years.
• Keep the subwoofer dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that corrode electronic circuits.
• Use and store the s ub w oofer onl y in norm al tem perat ure environments. Tem­perature extremes can shorten the life of electronic devices, and distort or melt plastic parts.
• Handle the subwoofer gently and carefully. Dropping it can damage circuit boards and cases and can cause the subwoofer to work improperly.
• Keep the subwoofer away from dust and dirt, which can cause premature wear of parts.
• To maintain the cabinet’s finish, do not let it come into contact with water vapor, alcohol, benzene, insecticide, or similar liquids. Do not place a plastic covering on top of the c abinet, as the plastic’s color could come off and stick to the finish. Clean the subwoofer cabinet with a soft, dry cloth.
• Never touch the subwoofer elements with your hands or expose them to excessive shocks. If the subwoofer is dented or bent, the sound is distorted as well.
Modifying or tampering with the subwoofer’s internal components can cause a malfunction and invalidate your subwoofer’s warranty. If your subwoofer is not performing as it should, take it to your local RadioShack store for assistance.
